HINGE FOR DOORS AND WINDOWS.

Application filed August 2, 1926, Serial No. 126,485,'a11d in Germany April 10, 1926.

This invention relates to a hinge for doors and windows which is constructed so that the open door or window can be securely locked in any open position. With this object in view the hinge p1n has horiaontal bores in that portion which is enclosed 1n the sleeve of the upper hinge band sa1d bores being displaced the one with regard to the other along an arc. The hinge pin has further an annular groove in its upper portion preferably at the middle of the helght of this upper portion.

In the sleeve of the upper h1nge band holes are arranged one for each bore of the hinge pin and one for the annular groove. A pin in the end of a blade spring pivotally fixed on the upper hinge band is des gned to be inserted in any of the holes of said sleeve so that, if it engages with said annular groove, the dOOr or window can be freely moved but is locked in the corresponding open position if said pin engages with one of the horizontal bores of the hinge pin.

An embodiment of the invention is shown, by way of example, in the accompanymg drawings in which Fig. 1 shows the improved dooror w1n- (low-hinge in elevation.

Fig. 2 is a section on line III I of Fig. 1.

Fig. 3 shows in elevation the hlnge locked in the open position.

Fig. 4 is a section on line IV-IV of s- Fig. 5 shows the hinge pm 111 elevation, the upper hinge band being removed.

The hinge for doors or windows comprises an upper hinge band a and a lower hinge band I) having each a sleeve 0, (Z respectively at the inner end. Into the sleeves '0, (Z a hinge pin 6 is inserted which has, in the portion enclosed in sleeve 0, horizontal bores f which are displaced radially the one with regard to the other. At a convenient point oii this portion of the hinge pin 0 an annular groove 9 is cut into the hinge pin, preferably at half the height of this portion. The

sleeve 0 has holes h, one for each bore 7 of,

the hinge pin, and one for the annular groove h.

On the up oer hinge band a. a blade spring 70 is pivotally fixed by means of a pivotaxle 2'. In the free end of the blade spring in a pin Z is fixed which is designed to be inserted into one of the holes 17%.

It the pin is inserted into the hole it which corresponds with the annular groove 9 its point will engage with this annular groove so that the upper hinge band can be freely moved with regard to the lower hinge band. If however the pin Z is inserted into one of the other holes ll of sleeve 0 its point will be pressed by spring 9 into engagement with that bore 7 of the hinge pin 6 which comes opposite the corresponding hole h, as soon as the door window has been opened accordingly so that the door or window is securely locked in this corresponding open position.

I clain'1:

A hinge for doors and windows comprising in combination, a hinge pin having in its upper portion horizontal bores displaced the one with regard to the other along a curved line and an annular groove, a lower hinge band fixed to the door case or window case and having at its inner end a sleeve placed over said hinge pin, an upper hinge band fixed to the door or window, a sleeve at the inner end placed over said hinge pin and having as many holes as there are bores in said hinge pin and one hole for said annular groove, a blade spring pivotally fixed at one end on said upper hinge band, and a pin fixed in the free end of said blade spring and designed to be inserted into one of said holes or" said sleeve so that it said pin engages with the hole for the annular groove the door or window can be freely opened or closed but is securely locked in any corresponding open position if said pin engages with one of the bores of said hinge pin.

In testimony whereof I aifix my signature.
